"NEW" Bundle-imaging Fiber Photometry System


Ordering Code:

 

  • Doric's Bundle-imaging Fiber Photometry System (BFMC) is fully integrated, offering a hassle-free, plug-and-play solution. To record green and red photometry signals, the BFMC uses built-in LEDs to illuminate the entire sample port, and a CMOS sensor to simultaneously image the fluorescent signal from every fiber within the bundle. The fluorescent light collected from each fiber within the bundle creates circular spots on a CMOS sensor. The electrical read-out from pixels within each fiber image correlates with the calcium activity of the corresponding brain site.

    The BFMC system is equipped with 8 Digital Input/Output (DIO) ports and a HD25 adapter for synchronization and closed-loop experiments with external devices such as behavior cameras, operant conditioning chambers, video tracking software, and optogenetic light sources.

  • The 1-colors Bundle-imaging Fiber Photometry System records activity-independent green indicator (i.e. GCaMP) fluorescence, excited by 405, 415, 425, or 440 nm light (isosbestic point), and its activity-dependent fluorescence, excited by 470 nm light, from several fiber-connected brain sites with a CMOS image sensor. The sites labelled with green indicators can be on the same animal or distributed over many animals. The respective excitations are interleaved or sequentially applied to separate activity-dependent and activity-independent fluorescence emissions.

    The system includes:
      • Bundle-imaging Fiber Photometry System
      • All required electrical cables and patch cord

    Optional items:
    Accessories:

  • The 2-colors Bundle-imaging Fiber Photometry System records activity-independent and activity-dependent fluorescence from a green indicator (i.e. GCaMP) and red fluorophore (reference or indicator).  The signals are collected from several fiber-connected brain sites with two CMOS image sensors for the green and red channels.  The excitation wavelength for the isosbestic reference can be selected between 405, 415, 425, or 440 nm, while the excitation wavelengths are 470 nm for the green channel and 560 nm for the red channel. The sites labelled with fluorophores can be on one animal or distributed over many animals. The respective fluorophore excitations are interleaved or sequentially applied to separate different fluorescence emissions.
